Article on “Statistical Sampling Plans for Medical Devices”

One of the important aspects of design control of medical devices is statistical sampling plans for medical devices. To gain an understanding of the idea of statistical sampling plans for medical devices, one needs to understand the process of medical device design controls.

Statistical sampling plans for medical devices needs to be seen in this background: Under Sec. 820.30 of Title 21 of Code of Federal Regulations (CRF) the FDA sets out requirements from medical device manufacturers -which want to market certain categories of medical devices in the US -for establishing and maintaining procedures to implements design controls into the device.

An understanding of design controls is necessary first

First of all, what are design controls? Design controls are linearly and logically described and recommended steps that manufacturers have to take for ensuring that they have developed what they meant to develop. In addition, design controls have to also be implemented to ensure that the final product is in line with the expectations and needs from the customer’s perspective.

Statistical sampling plans for medical devices come at a slightly later stage. Design controls pave way for the validation processes of design verification and design, which are done to ensure that the device design has met critical specifications or outputs and fulfill the requirements for the safety requirements, intended use, or specified application.

Verification and validation

This stage makes way for the next, which is fulfillment of design verification and validation (V&V), as required under Sec. 820.50 of 21 CFR. A core part of this code is the requirement from manufacturers for establishing and maintaining procedures to locate valid and proper statistical techniques for the process capability and product characteristics to be considered applicable. These are what constitute statistical sampling plans for medical devices

More of rule of thumb

Statistical sampling plans for medical devices need to be written and based on a well-established statistical foundation. However, the FDA does not prescribe a formal plan for writing down statistical sampling plans for medical devices. These are to be based more on rule of thumb. In other words, there are no acceptable limits violations under statistical sampling plans for medical devices. The statistical sampling plans for medical devices need to be implemented on a case-to-case basis, based on the device’s characteristics and features.

In arriving at statistical sampling plans for medical devices, the FDA sets out the following rule:

Statistics for Medical Professionals

Medical statistics, also called biostatistics, is an important area for medical professionals. Statistics and the medical professionals may not seem very easily associable with each other at first glance, but a deeper look suggests the connection between statistics and the medical profession.

Statistics is a set of data and tables. These figures are meant to offer understanding and perspectives on a number of issues. When it comes to the medical profession; statistics for medical professionals becomes very important to those in the field of public health. Every time a government or an international agency of a world body such as the UN undertakes a program on public health; statistics are of immense importance for medical professionals.

Many uses of statistics for medical professionalsStatistics for medical professionals is useful in helping them analyze public health issues. Detailed figures of the incidence of malaria for instance, are a very useful piece of statistics for medical professionals. This kind of statistics helps them determine the causes of the disease and helps them decide on the plan of action.

Statistics for medical professionals is also useful at the local level. A medical professional working in a town or village could benefit immensely when she has statistics meant for medical professionals. It helps the professional understand what local causes are giving rise to health issues. Statistics for medical professionals thus helps them tackle issues at the local as well as the global levels

A specialized fieldIn developed countries, statistics for medical professionals has become a full-fledged profession. It is finessed at graduate and postgraduate programs at which they study the essentials of statistics for medical professionals. They then carry out programs that are suited for their profession.

Statistics for medical professionals is used in a wide variety of disciplines. Usually, courses on statistics for medical professionals cover the following areas:

  • Data Analysis of statistics for medical professionals

Applied statistics for scientists and engineers

Applied statistics for scientists and engineers is necessary for a number of reasons. 21 CFR and guidance documents for the pharmaceutical, biopharmaceutical, and medical device industries specify the application of statistical methods for these functions:

o  Setting validation criteria and specifications

o  Performing Measurement Systems Analysis (MSA)

o  Conducting stability analysis

o  Using Design of Experiment (DOE) for process development and validation

o  Developing process control charts, and

o  Determining process capability indices.

Since scientists and engineers are at the heart of these functions, they need to have a thorough knowledge of how to use applied statistics. Each of these particular applications requires different and specified statistical methods. The common tools used for setting acceptance criteria and specifications are data and tolerance intervals, while for setting expiries and conducting stability analysis studies; simple linear regression and analysis-of-covariance (ANCOVA) are used.

For analyzing designed experiment for process development and validation studies, two-sample hypothesis tests, analysis-of-variance (ANOVA), regression, and ANCOVA are methods used, while for developing process control charts and developing process capability indices; descriptive statistics (distribution, summary statistics), run charts, and probability (distributions) are used.

Explaining the importance of applied statistics for scientists and engineers

A seminar that is being organized by GlobalCompliancePanel, a leading provider of professional trainings for the areas of regulatory compliance, will explain the importance of applied statistics for scientists and engineers.

In the course of making the importance of applied statistics for scientists and engineers known; the Director at this seminar, Heath Rushing, who is the cofounder of Adsurgo and author of the book Design and Analysis of Experiments by Douglas Montgomery: A Supplement for using JMP, and has been an invited speaker on applicability of statistics for national and international conferences, will provide instruction on applied statistics for scientists and engineers and statistical methods for data analysis of applications related to the pharmaceutical, biopharmaceutical, and medical device industries.

To enroll for this highly valuable and practical course on applied statistics for scientists and engineers, just register by visiting http://www.globalcompliancepanel.com/control/globalseminars/~product_id=900790?wordpress_SEO .

The course “Applied Statistics for Scientists and Engineers” has been pre-approved by RAPS as eligible for up to 12 credits towards a participant’s RAC recertification upon full completion.

The tools that help an understanding of applied statistics for scientists and engineers

This course on applied statistics for scientists and engineers will offer thorough instruction on how scientists and engineers need to apply the appropriate statistical approaches: descriptive statistics, data intervals, hypothesis testing, ANOVA, regression, ANCOVA, and model building. The Director will present the ways of establishing competence in each of these areas and industry-specific applications.

The application of statistical methods across the product quality lifecycle is specified in the 21 CFR and guidance documents for the pharmaceutical, biopharmaceutical, and medical device industries. There are many statistical methods that may be applied to satisfy this portion of the QSR. Yet, some commonly accepted methods can and should be used by all companies to:

o  Develop acceptance criteria

o  Ensure accurate and precise measurement systems

o  Fully characterize manufacturing processes

o  Monitor and control process results and

o  To select an appropriate number of samples.

At this seminar on applied statistics for scientists and engineers, Rushing will provide instruction on all these. He will cover the following areas over the two days of this seminar:

o  Describe and analyze the distribution of data

o  Develop summary statistics

o  Generate and analyze statistical intervals and hypothesis tests to make data-driven decisions

o  Describe the relationship between and among two or more factors or responses

o  Understand issues related to sampling and calculate appropriate sample sizes

o  Use statistical intervals to setting specifications/develop acceptance criteria

o  Use Measurement Systems Analysis (MSA) to estimate variance associated with: repeatability, intermediate precision, and reproducibility

o  Ensure your process is in (statistical) control and capable

Statistics for the Non-Statistician: Is it necessary?

Statistics for the non-statistician: Isn’t this some kind of a contradiction in terms? Why does a non-statistician need to rake his head over statistics? Is statistics a life skill or a lifesaving one? If it is not, why is statistics for the non-statistician necessary? At first glance, statistics for the non-statistician may appear unnecessary and redundant, but a slightly deeper look will make one understand that statistics for the non-statistician is indeed important, and has uses that help to make important contributions to the organization in which they work.

For understanding processes

Statistics for the non-statistician is important because we need statistics in the course of our professions while taking important decisions in business. For those working in the corporate world, statistics for the non-statistician becomes an important tool and skill with which a deeper understanding can be made of the statistical tools and techniques that employees routinely use in an organization. Using these tools, the professional has a greater understanding of the important parameters and pointers of the business and how to bring about improvements in the quality of a firm’s process and product.

Why statistics is important for the non-statistician can also be understood from the fact that when statistics is not properly analyzed, i.e., when statistical analysis is not performed insightfully as a result of a lack of full understanding of the statistical principles and processes by the employees; the organization faces a number of problems. These range from the possibility of facing the risk of producing a poor quality product. Such a product severely retards its ability to deliver a high quality product, as a result of which there is a heavy negative impact on the organization’s bottom line, as well as a blow to its reputation.

Get to understand the importance of statistics for the non-statistician

The importance of statistics for the non-statistician can also be understood from the fact that its knowledge helps regulatory professionals meet regulatory compliance requirements without hassles. To get a clear understanding of the ways in which statistics for the non-statistician helps organizations overcome many challenges, a seminar is being organized by GlobalCompliancePanel, a leading provider of professional trainings for the areas of regulatory compliance.

At this seminar on statistics for the non-statistician, Steven Walfish, the founder and President of Statistical Outsourcing Services, who brings nearly 20 years of industrial experience providing statistical solutions to complex business problems, will be the Director. To enroll for this seminar, please visit http://www.globalcompliancepanel.com/control/globalseminars/~product_id=900742SEMINAR?linkedin_SEO. The “Statistics for the Non-Statistician” has been pre-approved by RAPS as eligible for up to 12 credits towards a participant’s RAC recertification upon full completion.

It is all about practice

Practice is at the root of understanding statistics for the non-statistician. Constant practice is the mantra for employees to attain proficiency in statistics. They need a little bit of initiative, familiarity and some real-world example data sets. Employees who need training on statistics for the non-statistician need an understanding of the most common statistical tools and terms.

They need to understand

a.      how to use statistics to properly trend data

b.     support the annual product review

c.      justify process changes

d.     set product specifications.

The aspects of statistics that employees need to be familiar with

Employees who want to learn how statistics works for the non-statistician need to be able to make use of statistical software packages and understand the role of software in statistical analysis and statistical process control. They also need to have the skills necessary to design a statistically sound sampling plan that helps them comply with FDA APR requirements.

The result of this kind of familiarization is that organizations can perform their core functions and still be in alignment with statistical processes that are necessary for staying ahead of the competition. This is what statistics for the non-statistician entails.

The course on statistics for the non-statistician is immensely useful to professionals and supervisors in medical devices, diagnostics, pharmaceuticals and the biologics fields.

Getting Design of Experiments and Statistical Process Control right for Process Development and Validation

Procedures must be used in the application of DOE and SPC to the development, design and monitoring of manufacturing and testing processes. Why this needs to be done is because the FDA has, in a recent guidance document on Process Validation, assigned the responsibility for reviewing and interpreting DOE and SPC studies to the Quality Unit.

fda-round

Going about doing this work requires a practical orientation. It calls for an approach with case studies and examples. A seminar that is being organized by GlobalCompliancePanel, a leading provider of professional trainings for the regulatory compliance areas, will provide just this and fulfill this requirement.

Dr. Steven Kuwahara, Founder and Principal, GXP BioTechnology LLC, will be the Director at this two-day session. To enroll for this valuable session, please register by logging on to http://www.globalcompliancepanel.com/control/globalseminars/~product_id=900701SEMINAR. This seminar has been pre-approved by RAPS as eligible for up to 12 credits towards a participant’s RAC recertification upon full completion.

An interactive session

Dr. Kuwahara will offer theoretical information introduced only when necessary to understand an experiment. A highly interactive and practical session; this seminar offers examples from real processes and testing procedures and present the participants with examples that will be directly applicable to their work.

For any pharmaceutical worker who performs, supervises or reviews manufacturing or testing processes, an understanding of the relationships among the process parameters and the ability to monitor the performance of processes and test methods are necessary. This is all the truer of the worker in Quality Control and Quality Assurance in view of the recent FDA guidance document on Process Validation.

quality-management-2

This work, however, is done by the development, manufacturing, or quality systems worker. So, synchrony between these two levels of employees is needed. This course will equip these two levels of employees with the knowledge of how to design the systems and studies, and interpret the results generated.
